LOCOMOTIVE.

Application filed April 9, 1919; Serial No. 288,703.

To all whom it may concern:

Be it known that I, GEORGE H. F. HOLY, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Locomotives, of which the following is a specification.

My invention relates to industrial electrical locomotives and'particularly tostoragebattery locomotives for service in mines or other industrial properties.

One object of my invention is to so mount a driving motor as to permit a maximum range in gear ratio without reference to the diameter of the motor frame.

Another object of my invention is to provide a resilient supporting member for the driving motor that will permit of maintain- 0 ing a proper position of the motor with relation to its associated axle.

In storage-battery locomotives for mine service, it is desirable to have the total height as small as possible, and, it is, therefore, de-

26 sirable to make the frame of the locomotive as low as possible. If the storage-battery box is located between the two axles, it is desirable to mount the motors outside of their respective axles in order to shorten the overall length of the locomotive. If the motor frame is located away from the reduction gearing and has its shaft disposed transversely to the axle, it is possible to get a short distance between gear centers'without reference to the diameter of the motor frame, and also to apply a maximum motor capacity on a locomotive designed for a minimum-gage truck.

In practicing my invention, I provide a 4 single-truck locomotive in which the middle portion of the side frames is of low height to ermit mounting thereon a storage-battery liox of the full width of the truck. I pro vide also a driving motor pivotally con- 4 nected to its associated axle and yieldingly supported at its free end, with the motor located between its associated axle and the outer end of the truck frame, and with the motor shaft disposed transversely to its associated axle. I provide also a spur pinion and gear for the first reduction and a bevel pinion and gear for the second reduction, mounting the spur gear and the bevel pinion on a short shaft that is carried by the pivotal motor-supporting member.

In the drawing, Figure 1 is a plan view of the'apparatus embodying my invention, certain parts being omitted, and Fig. 2 is side elevation of the apparatus embodying my invention, certain parts being cut away;

Referring to Fig. 1, two side frames 10 are provided with end frames 11 and with suitably located cross members 12 to constitute a' rigid truck frame. Two axles 13, journaled in suitable bearings 14, are each pro vided with two driving wheels 15. A motor 16 is provided for each axle and is pivotally connected thereto by means 'of a supporting member 17 Thesupporting member. 17 at its axle end, is provided with two bearings 18 and is arranged, at its other end, to serve as a supporting member for the motor 16.

The motor 16 is detachably and longitudinally adjustably secured to the supporting member 17 by means of two essentially semicircular clamping members 19 and 20, which are pivotally connected, at one side of the motor, by a pin 21 and, at the other side of the motor, by. a suitable bolt 22, the member 20 being suitably connected to the supporting member 17. By this construction the motor 16 maybe quickly entirely removed from the frame 17 by removing the bolt 22 and swinging the upper clamping member 19; back upon its pivotal connection. Also, the motor maybe longitudinally adjusted for the proper intermeshing of the motor pinion 3 1 with-the spur gear 31, or entirely disengaged therefrom without removing the motor from the frame by loosening'the bolt 22. The supporting member 17 is provided, at its under surface, with a bolt 23 connected thereto by means of a stud or pin 24. A spring 25 surrounds the bolt 23 and is adapted to sustain the weight of the motor 16, through a washer 26, in contact with the under side of member 17. A nut 27 permits a slight com ression of the shaft, is a bevel pinion 32, also suitably secured thereto. Bevel pinion 32 meshes with a cooperating bevel gear 33 that is suitably secured to the axle 13. A spur pinion 34 is suitably secured to the shaft of the motor 16 to mesh with the spur gear 31. A cover 35 is suitably secured to the member 17 to 1 cover the spur gear 31.

all)

A storage battery 36, comprising a rela tively large number of cells, is mounted on the truck frame between the two axles and sets of driving wheels, and an additional storage battery 37 is located over each of the two axles 13. Suitably secured to the side frames 10 of the truck are upwardly extending brackets 10 which, together with the cross members 12, retain the battery 36 in a substantially central position and permit of constructing the storage battery 36 as wide as the widest part of the locomotive frame, a very desirable feature in locomotives for narrow gage roads.

By mounting themotor outside of the axles and away from the intermediate, shaft, the

distance betweenthe centers of the spur pinion and gear wheel may be made as small as desired without reference to the outside di ameter of the motor frame.

While I have shown a particular embodiment of my invention, various modifications may be made without departing from the spirit and scope of my invention, and I desire that only such limitations shall be placed ity of gear wheels and a shaft, and a frame pivotally mounted on each of said axles and detachably supporting said motors and permitting relative vertical movement of each of said axles and its associated motor.

2. In a locomotive, the combination with two axles, driving wheels mounted thereon, and a propelling motor connected to each axle, of means for pivotally supporting each motor on its axle and means for detachably mounting said motor on said supporting means, comprising semicircular clamping members having a hinged connection at one side of said motor and a releasable connection at the other side of the motor whereby said motor is detachably and axially adjustably secured to said supporting means.

3. In a single-truck storage-battery locomotive, the combination with two axles, driving wheels associated with said axles, a storage battery, a motor operatively connected to each of said axles, of side frames and cross-connecting members constituting a rigid truck frame, said side frames having upwardly extending bracket members intermediate the two axles between which the storage battery is located.

4. In a single-truck storage-battery locomotive, the combination with side frames having bracket members at the mid-length thereof, cross-connecting members to con stitute, with side frames, a rigid-wheel-base truck, axles, driving wheels associated with said axles, and a storage-battery box mounted between said bracket members intermediate said axles, of a driving motor operatively connected to each axle and located between its associated axle and the adjacent end of the frame, the shaft of said motor being disposed transversely to its associated axle and located in a plane above the plane of said axle, and means for yieldingly supporting said motor on said truck frame.

In testimony whereof, I have hereunto subscribed my name this 21st day of Man, 1919.
